BEDSPRING ANTISWAY DEVICE.

Application filed May 15, 1922. Serial No. 560,889.

bed springs and its particular value is in connection with that type ofspring in which the resiliency thereof is secured through the use of aseries of. coiled springs distributed over the supporting area.

The principal objects of the invention are to provider an improvedarrangement for bracing the edge or border of the spring against lateralmovement, while freely permitting vertical displacement thereof withoutsubstantially affecting its comfort or resiliency; to provide a deviceof the class described which shall be of especial value for springs ofthe double-deck type and in general, to provide an improved, economicaland efiicient bed spring of the character referred to.

In the drawings, which illustrate a preferred embodiment of my.invention as applied to a coiled spring construction of the double-decktype Fig. 1 is a plan view of the device;

Fig. 2, an elevation of same;

Fig. 3 a section taken on the line 33 of Fig. 2; and

Fig. 4 is a detail view.

Referring to the drawings, it will be observed that the supporting frameis comprised of a surrounding frame of angle iron,

one of the side members of which is indicated at 20. The horizontalflange of said angle iron20 constitutes a support for the ends of aseries of laterals or crossmembers 21. The intermediate portions of saidcrossmembers 21 are dis'posededgewise or with their major dimensionsvertical so as to furnish the desired strength" and rigidity, but inorder to facilitate connection to the angle iron 20 theends ofsaidcross-members 21 are turned to an angle of '90 degrees, as' indicated at22, thereby readily permitting said ends to be bent at 23 and 24, inorder to bring the outer ends of the cross-men'ibers at a higherelevation than the intermediate or edgewise "portions. Theout'erends25of said fiat- Wise portions of the cross-members are rivet ed, orotherwise suitably secured, to the horizontal flanges of the angle ironside members 20, and preferably the bends 24 are located some distancefrom the outer ends of said parts 25 so as to furnish a horizontal shelfor support for the outer rows of springs 26. It will be observed thatsaid springs 26 are of the single-deck type, whereas the intermediate orinner springs 27 are of the double-deck type.

The bottom coils of the outer springs 26 are secured to the portions 25of the crossmembers 21 by means of clips as at 29, said clips havingformed therein arched portions as at 30, suit-ably spaced to fit overand clamp diametrically opposite portions of the said bottom coil.

In springs of this general type, indicated herein, itis customar toequip the outer edge of the top of t e spring with a surrounding andusually continuous, border wire as at 35, said border wire beingsuitably united to the outer portions of the top coil of each of thesprings 26 in the outer rows.

My improved bracing means is used in connection with said border wire35'and is supported entirely upon the intermediate or supporting outerangle iron frame 20. The base for said bracing member comprises adownwardly and inwardly extending arm members 20, and these side wallsproject upwardly outside this flange to form a hook 39 (Figs. 2 and 4),firmly positioning the plate. The outwardly. turned edge flanges 40 onthe plate 36 are extended longitudinally at 41 and these extensionsoverlie and are riveted to the horizontalflanges of the side members 20at 42. The base plate thus comprises a pair of angles spacedapart toadmit the links and, integrally united at (their bottom edges. v

The links 37 and 38 have their lower ends ivoted'on pins or, rivets-43and 44 extendlng through the oppositely disposed vertical portionsv ofthe v of these links-37. and 38 are pivotally connected to pinsor-rivets .45 and 46 carried by a distance bar 47. This bar 47 is madeof a plate 36. The upper ends ends.

piece, of with the limbs of the U spaced apart a sufficient distance toadmit the upper ends of the links 37 and 38 in substantially the samemanner as the plate 36 at their. lower The upper end of the bar 47 isflattened out as to its lateral dimension, as shown in Fig. 1, in orderto furnish a relatively wide terminal portion, which may be foldedaround the border wire 35 so as to substantially embrace or enclose thesame, as indicated at 49. Preferably the border wire 35 is capable offree rotary movement in the socket thus formed.

, Upon inspection of Fig. 2, it will be observed that the inner end ofthe arm formed by the plate 36 is somewhat lower than the surroundingframe 20, that the link 37 is somewhat longer than the' link 38, andthat the space between the pivots 43 and 44 is somewhat greater than thespacing of the rivets 45 and 46 carried by the brace bar 47. Thedimensions and arrangement of the links and associated parts are such asto provide a system of linkage so organized thatthe border wire 35 whensubjected to external forces is compelled to travel in substantially astraightline perpendicular to the generalplane of the bed springs,lateral. movement or ing prohibited. It will be seen from inspection ofthe dotted line position of said partsthat when the linkage iscompletelycollapsed as is the case when the spring is compressed for shippingpurposes,.the border wire 35 is depressed mto a position substantiallyvertlcaly beneath its ordinary orand it will also be observed that thebrace bar 47 has assumed a substantially horizontal position where itopposes no obstruction to such complete depression of the coils of thespring.

Inasmuch as the abuse to which a bed spring of this type is usuallysubjected,

.either in service or in shipment, mainly cons1sts of blows or forceapphed in such a direction as to force the border wire 35 or other artsinwardly, I prefer to construct the 1' age and associated supports inthe best manner possible to resist such'inward movement of theborderwire. To this end, when shalping the ends of the vertical flanges of theas indicated at 50, so as to against thevertical flange of the saidframe 2 0. Such exlpedient furnishes a substantial addltlona amount ofstrength and rigidity as-againstrotary movement of the linkage systemaround the corner of the angle 11011 20 under the influence of blowstendmg to push the border wire inwardly. -Rotary vented by the hook 39.

ate 36 I cut the same slight? on the ang e, t up inwa Upward movement ofthe border wire is limited by the corner 51 of the link 38 engagingagainst the fold of the base arm. This feature, in combination with thehook 39 is of value when the bed-spring is lifted by the border wire.
